local area connection

Dobil sem ADSL. Do sedaj je delal brezhibno, zadnja dva dni pa se nekaj čudno obnaša! Na ikoni Loack area connection se pojavi tale napis:

Status: limited or no connectivy
You might not be able to access the internet or some networkresource. this problem occured because the network did not assign a network address to the computer.

Prosim za pomoč! Hvala
